Medication Verification via Unique Code Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for controlling prescription drugs are insufficient as they cannot verify individual pills, leading to potential substitution or illegal possession, contributing to the prescription drug abuse epidemic.
Innovation Solution
A coding system where medications are marked with a unique code, such as a QR code, linked to patient information in a prescription database, allowing for secure verification of pill ownership through a mobile app or device, comparing the pill code to the patient's ID.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prescription drugs are controlled through prescription requirements and databases, then drug distribution can be regulated, but individual pill verification is lost once pills pass the dispensary counter
Solution Approach 1:
The patent applies preliminary action by marking individual pills with unique identification codes (such as QR codes, data matrices, or other machine-readable symbols) during the manufacturing process, before the pills reach the dispensary. This ensures that identification information is preserved on each pill throughout the distribution chain, enabling verification at any point after dispensing. The unique code is embedded in the pill itself or its packaging, maintaining traceability from manufacturer to patient.
Solution Approach 2:
The patent implements feedback by creating a verification system where the unique pill code is scanned or read, and the information is compared against prescription database records. This feedback loop confirms whether the pill matches the prescribed medication for that patient, providing real-time verification. The system returns verification results to authorities or patients, enabling immediate detection of substitution or misuse.
2Reliability
If prescription databases store patient information and prescription details, then drug abuse can be monitored, but substitution of pills in prescription containers cannot be detected
Solution Approach 1:
The patent replaces manual or mechanical verification methods with automated optical or electromagnetic reading systems. Machine-readable codes (QR codes, data matrices, barcodes) are scanned using digital devices such as smartphones, tablets, or dedicated scanners. This substitution enables rapid, accurate verification without manual inspection, reducing complexity in the verification process while improving reliability. The digital system automatically compares scanned codes with database records, eliminating the need for manual record-keeping or visual inspection.
3Reliability
If unique codes are marked on each medication, then individual pill verification is enabled, but manufacturing and marking processes become more complex
Solution Approach 1:
The patent applies universality by using standardized machine-readable code formats (such as QR codes, data matrices, or barcodes) that can be manufactured using existing industrial printing and marking technologies. These universal code types can be integrated into current medication packaging processes without requiring entirely new manufacturing equipment. The same marking systems can be applied across different medication types and packaging formats, reducing the need for specialized production lines while maintaining individual pill traceability.
Data Source
AI summary
A system for verifying proper possession of a medication where a reader device scans a code printed on the medication to extract an embedded serial number. A first server queries a prescription database, which retrieves patient information associated with the embedded serial number. The patient information is returned to the reader device and a match determination is made. The patient information may include a name and photograph.
